Tomcat-session-redis configuration (Session sharing)

Tomcat-session-redis Configuration

Session persistence mechanism Three methods of implementation:

1. Session binding: Always direct requests from the same source IP to the same RS; no fault tolerance; lossy equalization effect (SH)

2. Session copy: Sync session between RS, each RS has all the sessions in the cluster; it is not applicable to scale clusters; must RS support (LBLCR)

3. Session server: Use a separate server to manage the session in the cluster; (single point of failure only)

Nginx-tomcat-redis (session sharing) Configuration Instance :

Environment: Two machines:

10.15.51.141:tomcata

10.15.51.222:TOMCATB, Nginx, Redis

Steps:

1. The required packages are placed in the Lib directory of the Tomcat directory (attached)

Commons-pool-1.6.jar

Jedis-2.1.0.jar

Tomcat-redis-session-manager-1.2-tomcat-7.jar

2. Configure the Conf/context.xml in the Tomcat directory to include the following:

<valve classname= "Com.radiadesign.catalina.session.RedisSessionHandlerValve"/> <manager classname= "COM.R Adiadesign.catalina.session.RedisSessionManager "host=" 10.15.51.222 "#redis地址 port=" 63 "#redis端口 database=" 0 "maxinactiveinterval="/> #session失效时间 (sec)

3. Nginx Configuration:

http{upstream AAA {server 10.15.51.222:8080;    Server 10.15.51.141:8080;    }server {server_name aaa.test.com;    Listen 80;        Location {Access_log logs/ning_access.txt;        Proxy_pass http://aaa; }    }}

4. Add the following to the two tomcat to facilitate testing

A provides testing:

# mkdir -pv test/web-inf/{classes,lib}# vim test/index.jsp<%@ page  Language= "Java"  %>
 B provides testing: 
 
# mkdir -pv test/web-inf/{classes,lib}# vim test/index.jsp<%@ page  Language= "Java"  %>

Access:
Http://IP:80/test or Http://IP/test
